Abstract: Disclosed are a structure with a substrate-embedded waveguide and a method of forming the structure. The waveguide includes cladding material lining a trench in a substrate, a core in the trench on the cladding material, and at least one cavity within the core. Each cavity extends from one end of the core toward the opposite end and contains a low refractive index material or is under vacuum so the waveguide is an arrow waveguide. An insulator layer is on the substrate and extends laterally over the waveguide and a semiconductor layer is on the insulator layer. Additionally, depending upon the embodiment, an additional waveguide can be aligned above the substrate-embedded waveguide either on the isolation region or on a waveguide extender that extends at least partially through the isolation region and the insulator layer to the waveguide.

Abstract: A lighting assembly includes a lamp alignment assembly for positioning the lamps after the lighting assembly is installed. The lighting assembly includes a ceiling pan for mounting to the ceiling support and a lamp assembly attached to the ceiling pan. The lamp assembly is adjustable in a transverse and rotational direction with respect to the ceiling pan. A stop member on the ceiling pan is received in an aperture in the lamp assembly to limit movement of the lamp assembly on the base. The lamp assembly is provided with alignment springs to align the lamp assembly at predetermined settings. A sight window is formed in the ceiling to visually set the lamp assembly in a selected position. A locking member on the lamp assembly locks the lamp assembly in a fixed position on the ceiling pan.

Abstract: A luminaire and lighting assembly is provided having a ceiling pan and a light assembly supported on the ceiling pan. The light assembly is rotatable and movable in a lateral direction on the ceiling pan to provide adjustment of the light assembly with respect to the ceiling pan. The light assembly includes an aiming device which allows the lamp to be adjusted about a vertical axis and about a horizontal axis for adjustment of the lamp. The aiming assembly includes a locking assembly which fixes the position of the aiming assembly to simultaneously prevent rotation about the vertical axis and about the horizontal axis.

Abstract: Techniques are disclosed for processing communications in a communication system switch in which one or more processing scripts are selected for application to one or more communications in accordance with weightings assigned to at least a subset of the processing scripts. Measurements are determined for one or more switch resources, such as central processing unit (CPU) utilization, associated with processing of the communications using the processing scripts, and the processing script weightings are periodically adjusted in accordance with the determined measurements. The system resource measurements may be generally characterized as comprising resource limit measurements, business objective measurements, or other types of measurements. The invention facilitates the processing of communications in the system switch and provides improved efficiency and reliability.

Abstract: A wall-washer lighting fixture is installed flush with a ceiling surface and directs light horizontally and vertically along adjacent wall surfaces, closely adjacent to the intersection between the ceiling and the wall surfaces in order to reduce to a minimum any shaded area along wall surfaces adjacent the intersection. The lighting fixture includes first lens elements oriented, located and configured for directing light toward first areas of the wall surface, spaced vertically downwardly from the intersection, and a second lens element located vertically lower than the first lens elements and oriented and configured for directing light toward second areas of the wall surface, located between the first areas and the intersection between the ceiling surface and the wall surface, so as to illuminate the wall surface more uniformly while reducing to a minimum any shaded area along the wall surface adjacent the intersection.

Abstract: A filter bag for a pool cleaning device includes a bag structure, formed of nylon mesh material, and a discharge opening, formed by a zipper. The zipper allows for temporary access to the interior chamber of the bag by opening the zipper.

Abstract: There is disclosed an arrangement for testing each portion of a system by stimulating at an interface of the system the expected responses. Software scripts are pregenerated and compiled into system message commands. Each script contains sequences of expected message responses as well as stimuli messages. The system is designed to use a single interface without regard to the type of simulated messages.
